Potassium Carbonate → (4-Hydroxyphenyl)(dimethyl)sulfanium methyl sulfate

Participants

Reaction Steps

The procedure of Example 7 was repeated with the exception that potassium carbonate was not used. The amount of the sulfonuim compound obtained was 2.99 g. An NMR analysis showed that the sulfonuim compound was a 33:67 (mol/mol) mixture of tert-butyl p-dimethylsulfoniophenyl carbonate methylsulfate and p-dimethylsulfoniophenol methylsulfate. The yields of butyl p-dimethylsulfoniophenyl carbonate methylsulfate and p-dimethylsulfoniophenol methylsulfate were 33% and 67%, respectively.
